After the 2008 presidential election, our government is leading our country to a new direction. On one hand, they have affirmed the determination of defending Taiwan; on the other hand, they have to create a win-win historical condition for the long-term peace progress of cross-strait relationship. This situation has certain influence on how the navy should prepare and arm itself. The Maritime Domain Awareness system developed by USNORTHCOM can automatically monitor the movements over waters and analyze any abnormal activities. In the future, it could also integrate with other military division awareness system, information combat system and other accessory functions. We should observe the measures and results of them in order to have a reference for our navy research and training units.
